Emacs is free to use the free C-x LETTER slots.  There were only 5 such 
free slots until a few days ago: c g j w x.

I agree with you that these free slots should probably be used as prefix 
commands.  I also agree with you that revert-buffer is perhaps not useful 
enough to use a single letter C-x slot.  I would suggest something like:

C-x g c = clone-buffer
C-x g d = diff-buffers
C-x g f = fit-frame-to-buffer
C-x g h = hexl-mode
C-x g i = insert-buffer
C-x g l = font-lock-mode
C-x g n = rename-buffer
C-x g r = revert-buffer
C-x g R = revert-buffer-with-fine-grain
C-x g t = toggle-truncate-lines

and so forth.
